DateTimePicker Control Overview (Windows Forms)

The Windows Forms DateTimePicker control allows the user to select a single item from a list of dates or times. When used to represent a date, it appears in two parts: a drop-down list with a date represented in text, and a grid that appears when you click on the down-arrow next to the list. The grid looks like the MonthCalendar control, which can be used for selecting multiple dates. For more information on the MonthCalendar control, see MonthCalendar Control Overview (Windows Forms).

When the ShowCheckBox property is set to true, a check box is displayed next to the selected date in the control. When the check box is checked, the selected date-time value can be updated. When the check box is empty, the value appears unavailable.
